结果：全玻璃体后脱离有明确的预防两个并发症的作用。
Results: This prospective study shows that total posterior vitreous detachment has a clear preventive effect on both complications.
在全部9例玻璃体机化膜及10例玻璃体后脱离病例均未探及血流。
No blood flow could be detected in all 9 cases of vitreous membranes and 10 cases of posterior vitreous detachment.
结果完全性玻璃体后脱离超声表现可见玻璃体后界膜回声，呈纤细波浪状，不与眼球壁相连；
Results Typical acoustic properties of complete PVD presented clearly the vitreous posterior boundary membrane echo, rugosity and slender wave form, which didn't connect with the eyeball wall;
玻璃体后脱离(PVD)能缓解甚至治愈部分眼底疾病，用于诱导玻璃体后脱离的方法有多种，但研究最多的是玻璃体腔内注射酶类药物。
Posterior vitreous detachment (PVD) can alleviate or even cure some retinal diseases. Several methods have been used to induce PVD, of which, intravitreal enzyme injection attracts the most attention.
结果：手术中发现15眼（71.4%）出现了不完全性的玻璃体后脱离（PVD），7眼（33.3%）有视网膜前膜形成，4眼（19.0%）发生视网膜脱离。
RESULTS: Incomplete posterior vitreous detachment (PVD) was found in 15 eyes (71.4 %), epiretinal membrane was formed in 7 eyes (33.3 %), and retinal detachment occurred in 4 eyes (19.0 %).
玻璃体脱离者见玻璃体形态失常，后界扁平与球壁间有液性暗区分隔。
Vitreous detachment displays abnormal shape presented as flat posterior boundary and fluid area between vitreous and eyeball.
彩色多普勒血流成像检查，后脱离的玻璃体上均无血流信号。
There were no flow signal in the vitreous detachment body in color Doppler.
结果显示：术中并发症为后囊混浊、虹膜粘连、玻璃体脱出、后弹力层脱离；
The result show that the intraoperative complications are post-capsule opacity, inis posterior synechiae, prolapse of vitreous and Descemet's layer detachment;
中心凹脱离，可见黄点，后玻璃体与内界膜附着。
Stage 1A: Foeal dehiscence, yellow spot, posterior hyaloids attached to ILM.
